Discharge electrode and plasma generating device

The invention relates to a discharge electrode and a plasma generating device, the discharge electrode is in a sheet shape, the thickness of the first end of the discharge electrode is larger than that of the second end, and the discharge electrode is suitable for being connected with the high-voltage end of a power supply module. Therefore, the second end of the discharge electrode has a smaller curvature radius, the discharge intensity of the discharge electrode can be effectively improved, high-concentration charged particles are generated, meanwhile, the discharge assembly is more resistant to electric corrosion, the intensity of the sheet-shaped electrode is higher than that of a filiform or needle-shaped electrode, the risk that the discharge electrode is snapped in the using process can be reduced, and the service life of the discharge assembly is prolonged. The service life of the discharge electrode and even the plasma generating device is prolonged, and the rejection rate of the plasma generating de
